An energy discharge system has been con- As a prelude to the system described in this strutted which permits repetitive pulses spaced paper, a conventional unipolar energy discharge 30 ms apart or greater to the Zero Gradient system, illustrated in Fig. 1, will be discussed. Synchrotron (ZGS) beam bumper magnet. To al-low beam bumping to either side of the equilibrium orbit, each pulse is independent in polarity and magnitude. Two pulses per machine cycle are provided, but the system is being expanded to five. The system consists of the beam bumper magnet time-sharing two independent energy storage sub-systems each containing two series ignitrons, one for each polarity and two crowbar ignitrons, one for each polarity. A logic system automatically triggers the crowbar associated with a given sub-system. An early crowbar trigger can be use
